After the most recent software update I am facing these issues :

1. Unstable connection :

Network keeps switching between 4g, 4g+ or 5g+ and 5g++. 

2. Performance Degradation:

They have definitely reduced /restricted performance which showcases during gaming (like BGMI) 

3. Camera performance was degraded and the app was laggy but they have fixed that in the latest update

although camera performance can be improved further. 

Requesting for these updates :

1. OIS support in 1080p 60fps video capturing. 

The hardware definitely supports this feature and since there is only 1 actually useful back camera I request you to provide this feature.

2. 90 Fps Support in BGMI 

 It is highly possible to enable 90fps gaming in BGMI through proper optimization. 

Although I donot think IQOO will do these upgrades as they are focusing on iqoo z9s, but if they do the above adviced upgrades then they will start a trend and will revolutionize entire smartphone industry.
